PPT-Geometry 1.5 Segment and Angle Bisectors

Bisecting a Segment The midpoint of a segment is the point that divides or bisects the segment into two congruent segments A segment bisector is a segment ray line or plane that intersects a segment . 14 p 22 V lwh SA lw lh wh A h V LA rh SA h r A lw p 2 l w A C a b 2003 by the Commonwealth of ginia Department of Education James Monroe Building 101 N 14th Street Richmond Virginia 23219 All rights reserved Except as permitt Horace, Stephen, Jon.
